Abstract
The existence of air pollutants and the unconstrained emission of
non-ionization radiation such as RF and UV radiation in the environment due to
various human activities eventually leads us to consider how necessary it is to
monitor the surrounding parameters to ensure the safety of the general public.
The basis of a monitoring system contains three prime subsystems namely the
detection sensor, wireless communication, and monitoring interface. This paper
describes an IoT-based system that consists of a set of interconnected
components that can detect, monitor, collect and store the data of parameters
such as UV radiation, RF radiation, gas leakage, and air quality from the
vicinity, in real-time. The system consists of 1) four distinct sensing modules
for measuring entities like air quality, gas leakage, UV, and RF radiation. 2)
a base station or a central unit mainly comprising of microcontroller ATMEGA328
and Wi-Fi module ESP8266 for the processing of data from the respective
sensors, to notify using buzzer alarm if the values cross the threshold limit,
and display of the values on LCD. 3) a cloud such as BLYNK and an android
application for real-time data collection and its visualization along with the
provision of remote access to the user. The complete description of the system
architecture is shown and the workability is proved.
